Kelly Clarkson is never offended by crazy rumors suggesting that she's lesbian. While many people think she's gay because she'd been single for too long, the "Breakaway" hitmaker admits that she doesn't feel insulted by those opinions. Still, the 30-year-old singer reveals that she once got hit on by "the hottest girl ever."

"People think, 'Oh, she's been single for too long.' That's kind of an insult to the gay community. Being single doesn't mean you're gay. But I'm never insulted by it, obviously," Clarkson opens up to Cosmopolitan. "I mean, I get hit on by the hottest girls ever. Oh, my god, if I were a lesbian, I would be so in luck. But it's just not my thing. I've always batted for the boys' team."

Asked if she also gets hit on by guys, the winner of "American Idol" inaugural season responds, "Yeah, I get hit on by both." She goes, "But usually the guys who hit on me are tools. It's the ones that don't hit on you that make you like 'Why didn't you ask me out?' It's like American Idol auditions: The guys who are the most confident are the horrible ones, and the ones who are good have no confidence at all."

During the chat, the Texan singer also dishes on her love story with her current fiance Brandon Blackstock, who happens to be the son of her own manager. "We've known each other for years, but we didn't start talking until the Super Bowl last February," she says. "And this is the funniest/worst thing ever: One of my superhero idols is Whitney Houston, and the day she died was our first date. I was like 'This is a bad omen'."

Though jokingly calling the beginning of her relationship a "bad omen," Clarkson confesses that everything turns great between her and Blackstock. "Oh, yeah. Six years I was single before this. I've never been truly loved like I am right now," she gushes.

Apart from talking about her love life, Clarkson dishes on her extreme weight loss. "One magazine said I lost 40 pounds - that's a small child, by the way. I lost 18 pounds," she says. "And I think that happens when you fall in love or date someone. If I'm going to be kissing or messing around, I gotta look good. There's not a fad diet."

"I was working with a trainer, and she said, 'You'd be amazed the amount of weight you can drop by halving your portions. I know it sounds crazy, but do it for two weeks and watch what happens.' I just cut back my portions, I stopped eating late at night, and I work out a little more than I used to, and I literally dropped 18 pounds in a month. I think it happens when you get really busy as well. But when I'm on my off-time - girl, those 18 might come back."
